The NAM forecasts the dry surface front to be pushing through northern Utah early tomorrow morning, so tomorrow is a day during which temperatures will struggle to rise.
By Monday morning, the upper level trough is centered near Vernal and 700-mb temperatures are dow to around -7ºC.
Such a temperature wouldn't be a record based on historical upper-air soundings, but is well below average.
And the NWS forecast shows how the bottom drops out after today.
Monday looks to be a below average temperature day statewide. Pity this system looks to only produce some snow showers and perhaps an inch or two of snow in the central Wasatch.
